When creating a custom food, is it possible to define servings in terms of liquid measurements (cup, fl oz, etc.) instead of grams? Cronometer allows me to create a Serving Size named "1 cup", but it still forces me to define that in terms of grams of the custom food in order to add additional serving sizes. If I'm adding a liquid, the nutrition label typically gives grams of fat, carbs and protein per cup or fl oz of liquid, meaning I would need to manually weigh the liquid to determine the number of grams if Cronometer is unable to allow me to specify servings in terms of liquid measurements.
Even better would be if Cronometer would automatically add a set of liquid measurements (cup, pint, tbsp, fl oz, etc.) after the user had specified nutrition data for one of them, as the relationship between these units is fixed.
I've been wondering the same thing! I'm glad I'm not the only one. Sorry I don't have an answer but I want to hear one
Here's an official response from Cronometer:
It seems there is something fundamental about the way their system is setup that dry measurements must always be used. It's annoying but I guess there's technically a workaround.
If you're going to use fairly large quantities of something in recipes, I recommend carefully measuring and weighing a specific volume to find the density and enter it appropriately. For things I don't use frequently and never in large quantity, I might just enter as 1 ml = 1 g (the density of pure water). Water based liquid foods will be a bit higher depending on the dissolved solids they contain (ocean water is about 1.03 g/ml). Syrups might be as high as 1.40 g/ml while beverages fall in the range 1.00-1.05 g/ml. Cooking oils tend to be about 0.92 g/ml.
Densities of many common foods can be found in this report (pdf) from the Food and Agriculture Organization of the United Nations
I agree that it would be nice if Chronometer provided convenient conversion between volumetric measures.
if Cronometer was smarter, they'd ask if the item was a liquid or a solid, and allow liquids to have ML & FL oz based measurements. (in addition to grams)
It's not that hard to give the user a more realistic user experience.
